Thread: New here, pics of my 98 GTP

Welcome!

Ask Away

Hmmm, well since my sig isnt showing up, here is a pic of my 87 Cutlass

Welcome to the forums!!! I've been through Erie many times. GTP/Cutlass are very nice loking cars. I have a friend here in town with 27thou original miles on his...same year. car is imaculate.

ask every and any questions you want. we are here to supply knowledge.

for minor upgrades to the GTP

1. Cold air intake(CAI)
2. PCM tune
3. 3.4 pulley
4. Ported exhaust manifolds, or headers
5. 3" down pipe(DP)
6. all the free mods.
7. 1.9rr

this should EASILY make your clean GTP a mid to high 13sec car in the quarter mile.

Thanks, this is going to be a big learning curve for me.

Funny thing is the Cutlass and the GTP both came from the same owner down in TN. I bought the 87 off him (he was the original owner of that as well) and liked how well he took care of it for 20 years, that when he decided to sell the GTP, I jumped on it, took a train down to Memphis and bought it, drove it home. Best drive of my life.

He is meticulous on taking care of his cars. So how could I go wrong.

Only ever worked on N/A engines, like my Cutlass. Never had to work with the computer in a car. lol Should prove to be interesting.

I am a Network engineer, so the computer stuff shouldnt be too hard. Just have to learn where to start. I am reading just about everything on this site, and have gotten a lot of good info so far.

I plan on starting slowly, just a few small mods, nothing crazy, and see where it goes. Leaving it stock looking though. No fancy body kits or anything like that here. Stock looking but fast is how I like it.

Nice Cutlass!

Tuners are a bit expensive, HP Tuners are $500 which allows you to hook up a laptop and change everything in the pcm and scan your car. $100 gets you a pcm with a base map for minor mods.

Stock trannies should be good to low to mid 13's depending on how much you beat it, some have gone low 12's on stock tranny but not for long.

A cold air intake, depending on where you get it, will cost you upwards of $100, some say wizair is best... or you can make it yourself, shown in the how to section here.

Exhaust modifications would be to get rid of that u-bend as it is the most restrictive, if you plan on going with a 3.4" s/c pulley, headers or downpipe and front ported exhaust manifold is needed. P.E.M.'s can be found for around $100, downpipes from $100 to $300?, Headers $350++.

A colder 180 t-stat, right plugs - Autolite 104's are popular and the stuff listed above should let you put on a 3.4" s/c pulley on your car and run safely.

After that, it's definitely headers, rockers/cam, intercooler, s/c porting, tb porting, but if you want to keep it close to stock I would just do some porting and rockers... Then your in the mid to high 13's depending on the pcm/tune.

Cool thanks for the info.

Cant wait for spring so I can do some much needed freshening up and finish my Cutlass rebuild.

Woo Whoo!!!! Another person with a Cutlass!!!! I'm not the only one anymore!!!

lol Thanks. I like your Cutlass.

What are the specs on it?

I just picked up a 403 this morning.

Nice cutlass, I had one years ago. I still have a 72 cutlass too.

I have to agree with the advice you've been given so far. They have you on the right track. I started out with a bone stock 99 GTP. I have had no major complaints or issues. Truly a great car and a few mods can really wake the car up.

Welcome!

Here is a link to my husbands homepage with pics and info on the Cutlass....
Trannymans Project Site

It has had a handful of different engines in it over the years including a number of 350 sbc engines, Olds 455, and currently a supercharged 3800 series 2 engine.

Welcome to the community.

Welcome to GPF!! Nice cars. I miss my 81 Cutlass I had years ago. White, custom white grilles, black wheels, dark tint.
